Provides Plug instrumentation via telemetry.

Plug pipelines are auto-discovered and instrumented.

We automatically gather:

• Transaction metrics and events
• Transaction Traces
• Distributed Traces

You can opt-out of this instrumentation via configuration. See NewRelic.Config for details.

To prevent reporting an individual transaction:

NewRelic.ignore_transaction()

Inside a Transaction, the agent will track work across processes that are spawned and linked. You can signal to the agent not to track work done inside a spawned process, which will exclude it from the current Transaction.

To exclude a process from the Transaction:

Task.async(fn ->
  NewRelic.exclude_from_transaction()
  Work.wont_be_tracked()
end)
